This sativa-dominant hybrid (sativa/indica ratio unknown) pays homage to Northern California's marijuana heartland. Humboldt County, together with Mendocino and Trinity counties, is part of the famed Emerald Triangle, the largest cannabis-cultivating locale in America. No one seems to know exactly where Humboldt the strain came from, aside from the fact that its parents provided both indica and sativa genes. The high is focused more in the head than in the body, though physical sleepiness is a common effect. Expect creativity, euphoria, and a boost of happiness. Humboldt can be used to treat depression, headaches, anxiety, insomnia, and lack of appetite. Its CBD levels are apparently quite low, however, so this isn't the best option for treating conditions that respond to that chemical, including epilepsy and other seizure disorders. THC is known to be fairly abundant, with levels topping 16% in some tests. That doesn't put this strain on the highest shelf for potency fans, but it's a highly effective treatment option for many patients.
